This 1957 Aston Martin DB Mark III is one of approximately 551 examples produced between 1957 and 1959. Chassis AM300/3/1480 underwent a refurbishment by Gentry Lane of Toronto, Canada, in 2016 before it was purchased by the selling dealer out of Canada in 2024. The car is finished in silver over burgundy leather upholstery, and power comes from a 2.9-liter inline-six with twin SU carburetors paired with a four-speed manual gearbox. Equipment includes a dual exhaust system, front disc brakes, 16″ wire wheels, Lucas driving lamps, and a sliding sunroof. This DB Mark III is now offered with refurbishment records and a clean Florida title.
The DB Mark III debuted in March 1957 as an evolution of the DB2/4 Mark II and shared much of its predecessor’s Tickford-built aluminum bodywork. Design cues introduced on the Mark III included a DB3S-inspired lower-profile grille, smaller door handle assemblies, and opening rear side windows. Three body styles were offered, with power from a choice of four versions of the 2.9-liter engine that was redesigned by Tadek Marek for the Mark III.
This example received bodywork and was repainted silver during the 2016 refurbishment. Features include polished bumpers with overriders, Lucas driving lamps with stone guards, a hood scoop, fender vents, and a sliding sunroof. An imperfection is noted on the hood.
The chrome wire wheels wear two-eared knock-off hubs and are mounted with 6.00–16 Firestone Deluxe Champion bias-ply tires. The independent front suspension incorporates trailing arms and an anti-roll bar, while the solid rear axle is located by a Panhard rod and parallel trailing links. Coil springs and Armstrong lever-arm shock absorbers are utilized all around. Stopping power is provided by front discs and rear aluminum drums.
The right-hand-drive cockpit features low-back bucket seats and rear seating surfaces trimmed in burgundy leather. Color-matched upholstery extends to the door panels, while black carpets line the floors. The selling dealer notes loose leather trim around the passenger-side quarter window hinge.
The DB Mark III featured a revised instrument arrangement that concentrated the gauges ahead of the driver. The three-spoke steering wheel wears a vinyl wrap, and it frames Smiths instrumentation including a 6k-rpm tachometer, a 140-mph speedometer, and combination gauges. The five-digit odometer shows 43k miles, approximately 10 of which were added by the selling dealer. Total mileage is unknown.
The 2.9-liter DOHC inline-six was an evolution of the W.O. Bentley-designed Lagonda engine that was re-engineered by Tadek Marek for use in the DB Mark III with a stiffened crankshaft and revisions to the cylinder head, cylinder liners, and timing chain. Equipment includes twin SU carburetors, a flip-up oil filler cap, and a spin-on oil filter conversion. The cylinder head was rebuilt during the 2016 refurbishment, and the engine was repainted at that time.
Power is sent to the rear wheels via a four-speed manual gearbox. Replacement clutch cylinders were installed in 2016.
